Re: How do i work out an average?

For my maths homework I need to find the average speed. I tried to add up and divide but the answer did not look right . Here are the speeds:20 km/h and 60km/h.I added up 20 and 60 and got 80 and then divided by 2. I them had 40km/h. As the question said that they travelled at 20 for 2 hours and 20 for only 30 minuets I do not see how 40km/h could be the answer.Help me please!

Average Nd arithmetic mean are the same thing.

What is your favorite color, by the way?

Hmm, a report is not a PM. Who was the user?
